Perhaps you should try some spelling variations:
yang wang » yang yang, yang guang, yang liang
yan wang » yuan wang, yang yang, qian wang
gan guan » yan guan, quan guan, fan guon
tan chia » tuan china, than china, can china
pei yang » wei yang, hui yang, pei yun
yan hua » tan hua, ya hua, wang hua
di long » i long, de long, ii long
long du » long d, long do, long run

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang wang) OR (yan wang))) OR (gan guan)) ((yan hua) OR (tan chia)) pei yang di long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang wang) OR (yan wang))) or (gan guan)) ((yan hua) or (tan chia)) pei yang di long du ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang wang) OR (yan wang))) or (gan guan)) ((yan hua) or (tan chia)) pei yang di long du ;*.
